TO ALL WHOM I T MAY C NCERN:

Be it known that I, WHLIABI SMEAD, 0f the-city of Rochester, in theState of. New York, have invented a, new and useful Universal-JointCouplinggfand I do hereby declare that the following is a full, clear,and exactV desription thereof, reference being had to the accompanyingdrawing,`mekingpa.rt of thisv specification,in which- Y A l Figure 1 isolongitudinal section, showing the clamping-bolt D and two ofthepivoting-points in elevation.

Figure -2 is a. view of the inside face of one-half of thecoupling-iron.

Like letters of referencel indicate corresponding parts, v V

The nature of this invention will be understood by reference tothedrawings and specifications.

To enable others skilled iu'the art to make and use my invention, willdescribe its construction und operation. A v

On the inside of the jaws A of an ordinii-ry universal-joint coupling,B, I east pivoting-points, C, and when they are put together they centreandere held together by a; coupling-iron, Bwhichihas recesses, d, castin it to receive them, asshown'in iig. 2. `The coupling-iron B is modein two parts, and held together hy a. bolt, D, and ou the inner face 'oflone-halfofthe coupling-iron B, I cast points e, sh'own in iig. 2, andin the other half I cust recesses to'reeeiv-e 'the same.` i i Theordinary universal-joint coupling is held together byholts passingthrough the jews andthe couplingiron, lwhich requiresthevdrilling ofeight holes, four in the jafws and four in the`coupling-iron, andbesides 'weakning the jaws,lit exposes the' lsoft iron of the parts towear, and requrestwo long bolts to el'et the joiningo the parts. In mydevice there are no holes t'o drill, and the hard-scale surface :of theparts is exposedV to the weer, which is preferble, and only requires a.short cla-mpfbolt, D, to hold it together.

' The object of this invention isv to produce a. cheap and efficientuniversal-jointleoupling.

WhtI eleim as my invention, end desire to securel by LettersFatigue-:isf-

The pivotingpoints 0,'cast ou the jzws of'an ordinary universel-jointeoupling," in combinationfwith the clamping-iron B, constructedsubstantially as herein described, and for the purposes set-forth. y
